Mathieu Malaterre 4c9847b737 dt-bindings: Remove leading 0x from bindings notation
Improve the binding example by removing all the leading 0x to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading "0x"

Converted using the following command:

find Documentation/devicetree/bindings -name "*.txt" -exec sed -i -e 's/([^ ])\@0x([0-9a-f])/$1\@$2/g' {} +

Broadcom Cygnus IOMUX Controller
The Cygnus IOMUX controller supports group based mux configuration. In
addition, certain pins can be muxed to GPIO function individually.
Required properties:
- compatible:
Must be "brcm,cygnus-pinmux"
- reg:
Define the base and range of the I/O address space that contains the Cygnus
IOMUX registers
Properties in subnodes:
- function:
The mux function to select
- groups:
The list of groups to select with a given function
For more details, refer to
Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
For example:
pinmux: pinmux@0301d0c8 {
compatible = "brcm,cygnus-pinmux";
reg = <0x0301d0c8 0x1b0>;
pinctrl-names = "default";
pinctrl-0 = <&i2s0_default>;
i2s0_default: i2s0_default {
mux {
function = "i2s0";
groups = "i2s0_0_grp", "i2s0_1_grp";
};
};
};
